Soot Question - 04 Taurus - Taurus Car Club of America : Ford Taurus Forum

TheB2B · 11-19-2012, 09:10 PM

Question on my motor, 2004 Duratec all original, replacing the spark plugs and found the back of the motor is heavily coated with soot. Not only the back of the motor but everything back their, any wiring, tubs, etc.

Question is, is this normal? I don't hear any exhaust leaks or any other strange noise. Heck the motor is actually very quite. ~134,000 and the only work I know of the transmission was rebuilt around 20,000 miles ago. I bought the car used and really like it.

Any thoughts or question please let me know.

No, you shouldn't have any soot back there. Only dust and road salt.

I don't think you could have an exhaust leak without hearing it. So my guess is it's some kind of other dirt or mixture with fluids.

As luck would have it, or bad luck, cylinder number four has a miss so I will be taking the UIM off to get to plug and determine if it is the coil(?) pack while I'm working on it I will get better access to the back of the motor and see what may be causing the problem. Hopefully I will figure it out. Let you all know what I do or don't find.

#4 is on the front side, so you shouldn't have to take the manifold off to get to the spark plug.

#4 cylinder is front pass.
